Helps protect home's piping system and plumbing fixtures 5 nominal micron rating For cold water only The Aqua-Pure Brand by 3M Whole House Replacement Filter, AP810 filter is a heavy duty, large diameter, graded density sediment filter cartridge. The AP810 water filter provides a rigid construction that helps to prevent collapse, and a porous cylinder that traps materials efficiently without affecting water flow. The Aqua-Pure Brand Filter Cartridge is a sediment cartridge made from an exclusive Progressive Porosity Process that entangles and entraps larger sediment particles toward the outer diameter and progressively smaller particles toward the cartridge core. This allows even loading for maximum cartridge life. In addition, the unique square-grooved surface provides more sediment-trapping surface area than ever before. Unlike string-wound and pleated paper cartridges, the rigid, sturdy construction of Aqua-Pure Brand cartridges are able to withstand variations in water pressure.
